4.1 Pin Descriptions
Table 1. Pin Descriptions
Pin Number Pin Name Pin Type Description
1 MagRngn Digital output / tri-state
Push-Pull output. Is ‘HIGH’ when the magnetic field strength is too
weak, e.g. due to missing magnet
2 PROG
Supply pin
Programming voltage input. Must be left open in normal operation.
Maximum load = 20pF (except during programming)
3 VSS
Supply ground
4 T3_SINn -
This pin is used for factory testing. For normal operation it must be left
unconnected. Inverse SIN (Sinn) output in SIN/COS output mode
5 T2_SIN -
This pin is used for factory testing. For normal operation it must be left
unconnected. SIN output in SIN/COS mode
6 T1_COSn -
This pin is used for factory testing. For normal operation it must be left
unconnected. Inverse COS (Cosn) output in SIN/COS mode
7 T0_COS -
This pin is used for factory testing. For normal operation it must be left
unconnected. COS output in SIN/COS mode
8 TC -
Test pin. Connect to VSS or leave unconnected
9 DX Digital output
Digital output for 2-wire operation and Daisy Chain mode
10 CLK
Digital input /
Schmitt-Trigger
Clock Input of Synchronous Serial Interface; Schmitt-Trigger input
11 CS
Chip Select for serial data transmission, active high; Schmitt-Trigger
input, external pull-down resistor (~50kΩ) required in read-only mode
12 DIO Bi-directional digital pin
Data output / command input for digital serial interface
13 VDD Supply pin
Positive supply voltage, 4.5V to 5.5V
14 C1
Digital input
(standard CMOS; no
pull-up or pull-down)
Configuration input: Connect to VSS for normal operation,
connect to VDD to enable SIN-COS outputs. This pin is scanned at
power-on-reset and at wake-up from one of the Ultra-low Power Modes
15 C2
Configuration input: Connect to VSS for 3-wire operation,
connect to VDD for 2-wire operation. This pin is scanned at power-on-
reset and at wake-up from one of the Ultra-low Power Modes
16 PWM Digital output
Pulse Width Modulation output, 2µs pulse width per step
(2µs ~ 512µs)
